USBA to DC Plug Fast Charging Power Cord — delivers DC 9V or 12V at up to 3A using Quick Charge 2.0/3.0 What this cable does and why you need it Converts power from a USBA Quick Charge (QC2.0/QC3.0) output into a DC barrelplug supply at higher voltages (9V or 12V). Ideal when you want to power or charge devices that require DC 9V or 12V from a USBA QCcapable charger or power bank. Eliminates the need for a dedicated wall adapter for many small DCpowered devices, simplifying travel, reducing clutter, and letting you use a single fast charger for multiple gadgets. Up to 3A output provides sufficient current for many small electronics that accept 9V/12V input while taking advantage of QC fastcharging negotiation for stable highervoltage delivery. Key features and attributes Output voltages: DC 9V / DC 12V (selected automatically when paired with a QC2.0 or QC3.0 USBA source) Maximum current: 3A Input interface: USBA (supports Quick Charge 2.0 / 3.0 protocols) Output interface: DC plug (for devices that accept a DC barrel plug at 9V or 12V) Functionality: Power conversion cable that negotiates QC protocols on the USBA side to supply higher DC voltages to devices with a DC input Performance: Designed to provide stable 9V/12V output when used with a QCcapable USBA charger or power bank Compatibility and important notes Works with USBA chargers and power banks that support Quick Charge 2.0 or 3.0 to obtain 9V or 12V output. When used with standard USBA ports that do not support QC protocols, the cable will not be able to negotiate higher voltages and will typically be limited to the charger's available USB output (commonly 5V). Confirm the DC plug polarity and physical plug size match your device before use. Common use cases Powering a portable router, wireless access point, or mobile hotspot from a QCcapable power bank while traveling. Supplying temporary or mobile power to small DC devices such as LED lights, mini fans, or monitoring equipment that accept 9V/12V DC input. Running test or bench setups where a compact QC USB charger is used instead of a bulky dedicated adapter. How to use Plug the USBA end into a Quick Charge 2.0 or 3.0 compatible charger or power bank. Connect the DC plug to the device that requires 9V or 12V DC input. Verify the device powers normally and that voltage/current requirements are within the cable's stated limits (9V/12V, up to 3A). This cable provides a practical, compact option for powering DC 9V and 12V devices from QCcapable USBA power sources. Always confirm compatibility with your device's power requirements before use.
